I'm a new user for BIRT report. Now I'm trying to create a Combo Box type parameter for some static selections by using BIRT 2.6.2. But unfortunately, It looks like not supporting accessibility. See my attached image for combo box. Moreover, the List Box type doesn't work either.

Do you any guy know how to make it support accessibility? Or it's a known issue for BIRT 2.6.2 version？
